what gaskets to use with aluminum heads?

74slnt6 said

about to put on the heads, first of all its a 69 HP 440, with 440 source aluminum heads. gasket thickness does not concern me, if anything right now i have a little too much compression. should i just use any gasket with some copper coat? thats what weve always done with the stock heads and its worked fine, should i do the same with the aluminum heads? anything i should know?

I talked with Ken at 440 Source about this same question, my friend uses the higher dollar gaskets from Felpro but I use their Blue Perma-torque gaskets with their heads. They told me that it depends on your compression ratio.
The higher dollar Felpro gaskets do overhang the combustion chambers on the heads but they also do on other heads also.
The high dollar head gaskets Fel-Pro Performance Z1009 - Fel-Pro Performance Head Gaskets, they overhang the combustion chamber.

The ones 440 Source suggested: Fel-Pro Q8553PT - Fel-Pro Head Gaskets
